application nea my as, ma man zo. naar.-

This invention relates to locks and pal'- ticularly to those of athiniiat character as used o'n bags, brief and suit cases, and similarcontainers.

Locks of this `type are required to be essentially simple, yetadequately fulfill thelr functionof security, and be susceptible ofconstruction at a low cost. Y

It is the main object of the present invention to provide a lockanswering the foregoing requirements, comprising only two operativepartsand an actuating sp Other advantages will become noticeab e in thefollowing detailed description, taken into connection withAV theaccompanying drawing, the same being part of this disclosure, and inwhich w Figure 1 is a front elevational view of an embodiment of theinvention, illustrating its application. Y Y

Figure 2 is a similar view of the lock and keeper drawn to an enlargedscale.

Figure 3 is a plan view of the lock mechanism showing the bolt in lockedent with the keeper.

Figure 4 is a similar'view of the same parts as disengaged.

Figure 5 is a plan view of the'lock Y back plate looking from the innerside.

Figure 6 is a transverse sectional view of theassembled lock. i Figures7, Sand 9 are perspective views of the slide bolt, swing tumbler and keyrespectively.

The numerals 10 andY 11 designate the body. and cover of a conventionaltype of container, the cover 11 having e 1 its meeting edge a keeper 12stru rectangular metal blank and bent to produce 40 a longitudinal loopits rear wall being sheared to form a pair of sharp prongs 13 to piercethe bag cover material and become upset therein upon pressing the loopwalls towards each other, firmly securing the `vl5 keeper body to thebag cover.

The bight of the loop thus formed is provided with two openings toreceive the 14 of keeper hooks 15 extending outwardly as shown, thestems14 being split and u set, drawing the shoulders o the hoo against thebight and holding the hooks rigidly.

The 'lock casing is composed of two sheet metal parts, its back plate16, having at its ends pairs of prongs 17 extending rearwardly andadapted to pass through the material of the bag body and thereafter bentto engage its innerside, anchorin the lock body rigidly to it inregister with t e keeper. siShort spacing lugs '18 .extend from theedges of the plate 16 at intervals and a similar lug 19 is inset fromthe left hand end adjacent the lower edge, which is provided withelongated lugs 20.

An elongated slot 21 1s formed through the plate 16 and an opening 22,both bein on its median line; near the right hand lower corner is asheared openin the material being extended inwardly orming a diagonallydisposed stop 23.

Reaching directly upward from the upper edge o@ the late are twoprojections 24 spaced 1n con ormity with the keeper hooks 15 .to guidethe same when entering the ca sing. '1s The other, outer part of thecasing conslsts of a plate 25 having a iange extending rearwardly fromeach of its four edges the flanges being suited to engage the edges ofthe plate 16, the lugs 18 to 2O of which seat vagainst the inner surfaceof the front plate 25 maintaining the plates in'spaced relation.

Raised from the upper edge flange is -a prong 26 and a pair of similarTongs are on the lower edge, these prongs ing bent to engage over theouter surface of the back plate 16 when the lock is assembled.

A iiat bolt 27 is slidably mounted between the plates 16 and 25, thesame having two undercut hooksw28 movable into and out of engagementwith the lukes of the keeper hooks 15, being reversed thereto, thekeeper hooks entering the casing through openings 30 in the upperflange.

The outer curved edge, cam-like, surfaces of the Yhooks 28 slide incontact with the ange on the upper edge of the casing and a curvedprojection 29 acting as a guide rides thereon A1n a similar manner, thuscausing the bolt to move in a straight path. l 'llx bolt is giaintainednoernally in a oc position y a two arm gun type spring31 disposedbetween the end ange of the casing and adjacent end of the bolt,thespring loo 32 being held in place by 10B the lug 19 of t e backplate.

Ret-raction of the bolt to permit locking ent of the hooks 15 and 28 isaccomlished by merely enterin the keeper hoo in the openings 30 anapplying a ne A the spring 31 `until the nioderate pressure, the curved,`cam-like edges of the hooks causin the bolt to o pose ukes of the lookspass each .other and sna into enga ment. TheA boltA 27 is norma lyretracte by a knob 33 having a stem 34 passing through a slot 35 in theplate 25 and riveted in the v bolt, the riveted portion findingclearance in the slot 21 of the back plate.

In order to hold the boltv 27 positively inv a locked position,incapable of being moved by' the Aknob 33, an angular notch 36 is formedin its outer edge near its curved projection 29, and engageable in thenotch is a detent 37 formed on aiiat tumbler 38,

pivoted on a pin 39 fixed in the back plate -the key is turned asindicated by the arrow in Figure3, or when the key is turned in areverse direction, as in Figure 4, the ward engages the projection 41,releasing the detent and swinging the tumbler a ainst the stop 23, thekey clearing the tumb er projections when in either position.

In order to prevent the tumbler from swinging or becoming accidentallydisplaced from its adjusted positions, the back plate has a raisedprojection 47 struck up to extend into the path of a corres endingprojection 48 on the under side o the tumbler 38, which, as beforestated, is resilient and permits snapping the projections past oneanother when the tumbler is actuated by a key, the full motion of thetumbler being limited by the bolt 27 and stop 23.

Although the foregoing is descriptive of the preferred embodiment of theinvention, it-will be vapparent that minor changes may be madeA in itsconstruction, without the exercise of'invention of conictin scope of theclaims hereto appen ed.

Having thus described my invention, what IA claim as new and desire tosecure by Letters Patent, is

1. A bag lock comprising a casing, -a keeper having elements enterablethrough said casing, a spring actuated-slide bolt having membersengageable with said keeper elements, said members acting as guides forthe bolt, a curved auxiliary guide at the front of said bolt, anangularnotch in the rear edge of said bolt, a key actuatedtumblerengageable in saidnotch, said tumbler being pivoted to the outer wall ofsaid casing and curved to conform with the curvature of the auxiliaryguide, a lug on said with the tumbler engageable in the notch in thebolt,

spring means for retainin said tumbler in either of two adjustedpositions, and means to manually move said. bolt when the pawl is disenaged. 4

2. bag lock comprising a casing, a keeper havlng hooks enterable throughlthe edgeof the casing, a springactuated bolt slidable in the casing,hooks on said bolt to engage the keeper hooks, said bolt hooks acting asguides for the bolt, a curved arm on said bolt extending into registerwith the ends of the hooks .thereon and' spaced to permit entrance ofone of the keeper hooks therebetween, an angular notch in the oppositeedge of said bolt disposed betweenthe arm and adjacent hook, a swingingtumbler having a detent t'engage said notch, said tumbler being curvedto conform to the curvature of the curved arm, a stop for said tumbler,detents to retain said tumbler in engaged and disengaged positions, andkey operated means for moving said tumbler into elther position.
